In order to provide in an encapsulated pressurized gas insulated high voltage installation having multiple bus bars an interruption point in line with every current carrying conductor, which can be bridged by a movable conductor part and which forms a gap in a first end position of this conductor part, both conductor ends are surrounded by a shield which defines the gap. The movable conductor part rests in a second end position against an insulating sleeve and is brought through an insulating bearing ring. In the first end position, the movable conductor part is contained in a recess in an end of one of the conductor parts. The movable conductor part has an engagement surface for allowing a tool to grasp the movable conductor part to move it so as to bridge the gap.

Encapsulated pressurized gas insulated high voltage installation

In a metal-clad, compressed gas-insulated high-voltage switching installation, installation parts can be cut off by a circuitbreaker and connected to the grounded casing by means of a grounding switch, insulated measuring electrodes connectable to the testing terminal of a capacitive voltage divider and to a display device being provided in the casing adjacent to the grounding switch, for observation of the conductor voltage. To obtain a simple test setup in a three-phase clad installation, two pin-type measuring electrodes are arranged respectively centrally between pairs of the three conductors in such a way that their rounded end protrudes into the interior of the casing.
